According to the Norse mythology, Odin is the son of Bor (father, one of the first Asgardians) and Bestla (mother, a frost giantess), and the full brother of Vili and Ve. With the aid of his brothers, a young Odin defeats the fire demon Surtur;[1] later, Odin reveals that his brothers were killed by Surtur, but gave their power to Odin. Later Surtur was imprisoned inside the Earth.[2] Odin thereafter became ruler of Asgard, where he received the epithet of All-Father, and eventually fell in love with the elder goddess, Gaea, by whom he is the father of Thor. After Thor's birth, Odin returns to Asgard, where his wife, Frigga, acts as Thor's mother. Odin is also the adoptive father of Loki, a child of Giant ancestry whose father King Laufey is killed by Odin in battle:[3] adopted in a deal with Bor's spirit, unaware of Bor's intention that the child would bring about Odin's downfall.[4] Despite Odin's intentions, Thor and Loki become bitter enemies. Odin also was the father of Balder by Frigga.[5]

Thor's preoccupation with Midgard (Earth) is a constant annoyance to Odin who, as punishment, has deprived Thor of his powers on at least three occasions, on which Thor's with his willingness to atone for his transgressions, his continued noble intentions, and his bravery, eventually convince the All-Father to restore Thor's original powers and identity.[6][7][8]

As ruler and protector of the Asgardian people, Odin has been involved in a number of crises that have threatened Asgard and, on occasion, Earth. Notable examples included stopping Loki, the Storm Giant Skagg, and Surtur (with the aid of Thor and Balder);[9] defeating the Absorbing Man after he absorbs almost all of Asgard;[10] banishing the monster Mangog;[11] sacrificing his right eye to Mimir for the wisdom to stop Ragnarök (Twilight of the Gods);[12] attempting to stop the Celestials in the armor of the Destroyer;[13] engaging inter-dimensional tyrant Dormammu in a "cosmic chess" match as champions of Master Order and Lord Chaos respectively,[14] and preventing Surtur from lighting the Sword of Doom, Twilight.[15]

Odin has also died three times in defense of Asgard. On the first occasion, Odin is killed by Mangog, and later revived by Hela.[16] On the second occasion, the Celestials melt the Destroyer, and thus stifle all Asgardians except Thor, who collects a portion of energy from each pantheon and uses it to revive Odin, who in turn resurrects the Asgardians.[13]

The final occasion involves a massive battle against Surtur on Earth, with Odin apparently dying once and for all, when the Odin Force—the source of Odin's power—migrates to his son, Thor.[17] As Thor eventually destroys the Loom of Fates and stops Asgard from perpetuating Ragnarok—which ends the entire Norse pantheon and Asgard itself—Thor believes Odin may be dead permanently. The Odin Force appears to him in humanoid form and says that this was Odin's plan all along.[18]

When Thor returns from hibernation in the void,[19] he begins to find the lost Asgardians,[20] but does not search for his father. During his Odinsleep, Thor finds Odin in a limbo wherein every day he does battle with Surtur. Odin declines Thor's offer of taking his place—noting that just Thor's offer has broken Bor's curse that he would be abandoned as Bor was—and states that Thor must lead the Asgardians, while Odin continues in a state approximating the Asgardian equivalent of heaven, to prevent Surtur from reentering the world.[4] Loki assuages Dr. Doom's fears about Odin's potential wrath if the Asgardians move to Latveria, assuring him that "Old One-Eye is yesterday's god" and "a relic".[21] Later, Odin's absence from the Nine Worlds leads his revived father Bor to wage battle against Thor, in which he is killed, and thus provokes Thor's exile for regicide.[22]

Odin returns from the dead after Asgard is invaded by the World-Eaters.[25]

During the Fear Itself storyline, Odin senses the return of his elder brother, Cul, the Serpent: God of Fear. After a brief monologue with Uatu the Watcher, Odin commands his people to return to the Asgardian plane against the protests of Thor,[26] and Asgard rebuilds into a war engine with which he intends to raze Earth completely, to destroy the Serpent. Thor convinces Odin to send him back to Earth instead,[27] and Iron Man travels to Asgard-space for an audience with Odin,[28] wherein Iron Man asks Odin if he can use one of Asgard's workshops to make weapons,[29] and Odin allows him to use the Workshops of Svartalfheim, to stop the Serpent before his shadow falls on the World Tree.[30] Captain America and the Avengers bring an unconscious Thor to Broxton so that Odin can heal Thor. As he tends to his son, Odin confesses that he has always tried to prevent Thor's prophesied death by the Serpent, not to prevent Ragnaraok, but because he loves his son and does not want to see him perish.[volume & issue needed] Odin prepares Thor by giving him the armor and helmet that he himself wore the last time he cast out the Serpent and gives Thor the Odinsword named Ragnarok (which was forged to end all things).[31] While Thor kills the Serpent at the cost of his own life, Odin frees those affected by the Hammers of the Worthy, and returns to Asgard with the corpse of the Serpent sealing off Asgard from Hermod and a number of other Asgardians left on Earth.[32]

During the Original Sin storyline, it is revealed to Thor that Angela is the daughter of Odin and Frigga; "killed" as an infant during Asgard's war with the Angels of the Tenth Realm, whereupon Odin severed the tenth realm from the other nine as "punishment".[33] Odin was later freed from his self-exile by Loki as he is set to return to Asgard.[34] The fight between Thor and Angela is interrupted when Odin recognizes Angela as his daughter, and reveals Angela's true history, wherein an Angel raised her as one of the Angels under the name of Angela. Due to her services for the Angels, the Queen pardoned Angela her life, but exiled her from Heaven for her lineage. After leaving Heaven, Odin tells Thor, Loki, and Angela that he still loves his children.[35]

Angered that someone else is wielding Mjolnir, Odin sends the Destroyer after the new female Thor, appointing his brother Cul Borson as his new 'Minister of Justice' to enforce his new decrees and operate the Destroyer, but Odinson and Freyja assemble an army of female superheroes to aid her,[36] forcing Odin to stand down.[37]

During the "Last Days" part of the Secret Wars storyline, Odin dreams of the end of all existence in an event greater than Ragnarok. When the Asgardians gather to witness King Loki (a more evil version of Loki from an alternate future) on the back of the Midgard Serpent where they believe that this will be their end, Odin and Freyja appear with machine guns to defend the Asgardians.[38]

As part of the All-New, All-Different Marvel, Odin has become a tyrant ruling Asgard with an iron fist ever since Thor Odinson went missing. He makes use of the Thunder Guard and the Destroyer Armor to protect his kingdom and even went so far as to imprison Frigga and anyone who gets in his way.[39]

As King of the Norse Gods, Odin possesses vast strength, stamina and durability far greater than a normal Asgardian, along with resistance to all Earthly diseases and toxins, incredible resistance to magic, and courtesy of the Golden Apples of Idunn, a greatly extended lifespan. Odin has all the abilities of his son Thor, but to a much greater degree. Odin is capable of manipulating the Odin Force—a powerful source of energy—for a number of purposes, including energy projection; creation of illusions and force fields; levitation; molecular manipulation, communicating telepathically with other Asgardians even if they be on Earth and he in Asgard,[40] hypnotizing humans;[9] channelling lightning to Earth from Asgard,[40] controlling the lifeforces of all Asgardians, and teleportation. The character has also used the Odinpower for greater feats such as transporting the entire human race to an alternate dimension;[9] stopping time;[9] pulling the remains of distant planets down from outer space to crush his foes,[1] compressing the population of an entire planet into a single being, the Mangog and then recreating the race[41] and taking a soul away from the arch-demon Mephisto.[42] The Odin Force extends Odin's power to a cosmic level,[43] allowing him to engage entities such as Galactus on their own terms.[volume & issue needed]

In battles against opponents of similar power, Odin carries the magical spear Gungnir ("The Spear of Heaven"), an artifact made of the metal uru, that can be used to channel the Odin Force. Even without the Odin Force it can still match Thor's hammer in battle. Once a year, during the Asgardian winter, Odin must undertake the Odinsleep for 24 hours to regenerate (and is closely guarded as he is vulnerable during this period), although he can be wakened by potent spells, such as those of Karnilla the Norn Queen.[44]

Odin is also a master tactician and schemer, and has prevented Ragnarok,[45] and planned for centuries for the coming of the Celestial Fourth Host.[46][47] The character also on occasion uses the eight-legged steed Sleipnirthe and the enchanted ship Skipbladnir, which can navigate the "sea of space" and be shrunk to the size of a toy.

In the Ultimate Marvel imprint, Odin is referenced as far back as The Ultimates (mostly by Thor),[48] but the way the series is initially written leaves the reader unsure whether or not Odin or Asgard actually exist as Thor is portrayed as human with Norse God delusions and technology that gives him his Godlike powers. In the final issue of The Ultimates 2, Thor proves his claims to be a genuine god by summoning an army of Asgardian warriors to help the Ultimates defeat Loki's army of monsters. Thor references Odin in his last conversation with Loki before he destroys him, sending him back to Odin. When the Ultimates begin to be financed by Tony Stark after their retirement from S.H.I.E.L.D., Thor informs that this is indeed the will of Odin.[49]

In Ultimate Comics: Thor, a prequel to The Ultimates, Odin explains to Thor that he is Asgard, and when he dies Asgard will be destroyed with him. He also informs that the Norn Stones and Mjolnir are extensions of his own power. When Loki leads an army of Nazi Stormtroopers and Frost Giants to invade and destroy Asgard, Odin forces Loki into the Room With No Doors and is killed in the battle with Mammoth. Asgard disintegrates around him with Thor giving one last powerful strike at his enemies. In present day, leading up to The Ultimates, Thor and Balder are reincarnated as mortals and Balder (reincarnated as the Ultimate version of Donald Blake) explains that the Gods are to be restored and Odin will return to rule Asgard again.[50]

He is later killed in Ultimate Comics: The Ultimates but unlike the tradition of Ultimate Marvel characters to remain deceased, Odin and the other Asgardians are still active (of sorts), as they appear to Thor in visions and act as a sixth sense for him. This is because Thor has "become Valhalla".[51]

Odin appears in The Super Hero Squad Show episodes "Mental Organism Designed Only for Kissing", "Mother of Doom", "Support Your Local Skyfather", and "Lo, How the Mighty Hath Abdicated", voiced by Jess Harnell.

Odin appears in the Guardians of the Galaxy episode "Stuck in the Metal with You."[citation needed] The memories of the Destroyer Armor showed how Odin once used it in battle. Odin is later seen in his Odinsleep at the time when Loki and the Destroyer Armor returned to Asgard. Loki tells Odin that the Guardians of the Galaxy have taken the Destroyer Armor disrupting the peace deal with Spartax and that they must be dealt with.
